Vegan Pizza?

Pizza is one of my favorite foods and I just haven't been able to find anything quite as satisfying as the greasy, real cheese topped, far from vegan pizza.  Vegan cheese just doesn't melt and the texture is less than appetizing. I made a great pizza sauce but the end product was a complete fail.  I think I might give it one more go but omit the cheese and just have a variety of veggies.  If that doesn't work, I'm not sure I can give up my traditional pizza forever.
